​ The answer that we get is 25. Can anyone verify that answer because I can’t understand that how after 25yrs the age of the son will be 3/5 of his father. I saw a few answers but I really can’t understand them though technically whatever they’ve done is totally correct.

  1. Answer:

    first : father age is 50 so son age is 20 ( because of 2/5 ratio )

    second : for calculation when father and sons age ration become 5/3 its take x years

    so after x years sons age will 20+x and father’s age will 50+x

    5/3 = 50+x/20+x

    5(20+x) = 3(50+x)

    100+5x = 150+3x

    5x – 3x = 150-100

    2x = 50

    x = 25

    after 25 years ration become 5/3

    i hope my answer help u..

    so like ans..
